Definitions
- This invention relates generally to the field of coaxial cable connectors and more particularly to a contact connector assembly for use with coaxial cables having a center conductor.
- Corrugated coaxial cables are electrical cables that are used as transmission lines for radio frequency signals. Coaxial cables are composed of an inner conductor surrounded by a flexible insulating layer, which in turn is surrounded by a corrugated outer conductor that acts as a conducting shield. An outer protective sheath or jacket surrounds the corrugated outer conductor.
- a corrugated coaxial cable in an operational state typically has a connector affixed on either end of the cable.
- the quality of the electrical connection between the coaxial cable and the respective connectors is of utmost importance. Indeed, the quality of the electrical connection can either positively or negatively impact the resulting electric signal as well as the performance of the connector.
- One issue that negatively impacts the electric signal between the cable and the connector is the size of the connector in relation to the size of the cable.
- specifically-sized connectors must be chosen for each size of cable that they are to be connected to. Improperly-sized connectors, or even improperly-selected connectors for a certain-sized cable, will negatively impact the electric signal between the cable and the connector, resulting in extremely low performance.

- a deformable washer 130 is positioned, in the first state, within the connector 10 between the second end 24 of the conductive tubular body 20 and the first end 92 of the expandable clamp 90, such that the deformable washer 130 engages the first end 92 of the expandable clamp 90 and engages the second end 24 of the tubular connector body 20.
- the deformable washer 130 being engaged by the tubular connector body 20, resists the axial force 93 and prevents the expandable clamp 90 from being advanced axially by the inserted cable end 210.
- the deformable washer 130 also acts as a bearing against which the first end 92 of the expandable clamp 90 slides as the expandable clamp 90 radially expands and contracts as exposed corrugations 214 and 220 pass through the second protruded edge 102, as described above.
- the expandable clamp 90 may be comprised of a plurality of sectors, for example sectors 104 and 106, that individually radially displace in relation to one another as the corrugated cable 200 passes therethrough.
- the plurality of sectors collectively comprise the expandable clamp 90, including the central annular recess 100, the first protruded edge 98, and the second protruded edge 102.
- the expandable clamp 90 may be further comprised of an elastic member 108 disposed around the radially displaceable sectors 104/106, thereby retaining the relative position of the sectors 104 and 106 with respect to one another, including during the radial expansion and contraction capability when the corrugation 214 and/or 220 of the prepared cable end 210 passes through and/or into the clamp 90.
- the elastic member 108 may be formed as an elastic ring.
- the elastic ring 108 may have a circular cross-section as shown in FIGS. 3 and 4, or the elastic member 108 may have a square, rectangular, or other cross sectional shape.
- the expandable clamp 90 may be provided on its outer periphery 95 with a correspondingly shaped groove which engages and the elastic member 108 and maintains the relative position of the elastic member 108 in relation to the clamp 90.
- the elastic member 108 may be made of an elastomer such as a rubber.
- the elastic ring may be made of rubber or a rubber-like material.
- the elastic member 108 may be formed as a toroidal spring, such as a wound metal wire spring commonly used in lip seals.
- the elastic member 108 may be formed as an elastic sleeve, which encloses a portion of the outer periphery 95 of the expandable clamp 90.
- the elastic sleeve may also be made of an elastomer such as a rubber.
- the prepared cable end 210 and the connector 10 are shown in the first state.
- the expandable clamp 90 has expanded radially to allow the first exposed corrugation 214 of the cable 200 to pass therethrough, and then contracted radially to contain the second exposed corrugation 220 of the cable 200 within the central annular recess 101 of the clamp 90.
- the exposed first corrugation 214 of the cable end 210 is disposed within the annular volume 89 formed between the first end 92 of the expandable clamp 90 and the second surface 86 of the compression ring 80, and the tubular mandrel 46 extends axially within the annular cavity 224.
- the expandable clamp 90 of the connector 10 retains the cable 200 in place.
- the cable 200 advances therewith due to the structural engagement of the expandable clamp 90, the compression cap 60, and the outer conductor 206.
- the connector 10 and cable 200 are positioned for the compression cap 60 and the tubular connector body 20 to be further axially advanced toward one another. This is achieved by one of the following: the compression cap 60 being axially advanced toward the connector body 20 as the connector body 20 is held in place; the connector body 20 being axially advanced toward the compression cap 60 as the compression cap 60 is held in place; or each of the compression cap 60 and connector body 20 being axially advanced toward one another concurrently.
- the axial advancement of the compression cap 60 and the connector body 20 towards one another results in the compression cap 60 and the connector body 20 reaching a second state, wherein the cable 200 within the compression cap 60, the compression cap 60, and the connector body 20, are sufficiently coupled mechanically and electrically to allow the cable 200 to pass its signal through the connector 10 to the port (not shown) to which the connector 10 is attached.
- the connector 10 in the second state, as shown in FIG. 5, the connector 10 establishes the desired operational electrical and mechanical connections between the cable 200, the connector 10, and the port (not shown).
- the compression cap 60 and the tubular connector body 20 are structured to slidably engage one another and move in an opposing axial direction with respect to one another from the first state of FIG. 4 to the second state of FIG. 5.
- the axial advancement of the compression cap 60 toward the connector body 20 facilitates the expandable clamp 90 moving axially within the inner bore 26 of the tubular connector body 20 toward the conductive compression ring 80.
- This axial displacement of the expandable clamp 90 results in the expandable clamp 90 deforming an inner region 132 of the deformable washer 130, such that the expandable clamp 90 axially advances past the washer 130 through the deformed inner region 132 of the washer 30 toward the compression ring 80.
- first exposed corrugation 214 of the outer conductor 206 of the coaxial cable 200 collapsing between the compression surfaces, or between the first end 92 of the expandable clamp 90 and the second surface 86 of the conductive compression ring 80.
- the compression surfaces described above, collapse the first exposed corrugation 214 into a collapsed corrugation 215, the collapsed corrugation 215 being defined as the entire section of the first exposed corrugation 214 that has been folded upon itself, or buckled upon itself, to create a double thickness of the outer conductor 206.
- the collapsed corrugation 215 comprises two thicknesses of the outer conductor 206 in at least a portion of the collapsed corrugation 215. In another embodiment, the collapsed corrugation 215 comprises two thicknesses of the outer conductor 206 in a majority of the collapsed corrugation 215. In yet another embodiment, the collapsed corrugation 215 comprises two thicknesses of the outer conductor 206 in the entirety of the collapsed corrugation 215.
- the compression surfaces further press the collapsed corrugation 215 therebetween to facilitate a functional electrical connection between the corrugated outer conductor 206 of the cable 200 and the tubular connector body 20.
- the tubular mandrel 46 extends axially into the annular cavity 224, thereby insulating the corrugated outer conductor 206 from the central conductor 202.
- the compression ring 80 against which the collapsed corrugation 215 is pressed in the second state, may further comprise an annular recess 88 in the second surface 86, the annular recess 88 being structured to receive the leading edge 226 of the first exposed corrugation 214, as shown in FIG. 4. Under the condition that the connector 10 is transitioned from the first state to the second state, the leading edge 226 enters the annular recess 88. The axial movement of the compression surfaces, 92 and 86, toward one another results in the leading edge 226 engaging the annular recess 88 and buckling within the annular recess 88 to assume the shape of the annular recess 88.
- the remaining portion of the collapsed corrugation 215 is compressed between the compression surfaces, 92 and 86, such that the collapsed corrugation 215 is buckled on itself between the compression surfaces 92 and 86.
- This two-stage buckling of the collapsed corrugation 215 enhances the electrical and mechanical connections between the corresponding components of the connector 10.
- the expandable clamp 90 may be further comprised of a beveled edge 110 proximate the first end 92, which facilitates displacement of the deformable washer 130 when the compression cap 60 is axially advanced toward the connector body 20, as explained above.
- the inner region 132 of the deformable washer 130 may be provided with score marks, slits, or other stress-concentrators (not shown) to facilitate the deformation of the washer 130.
- the deformable washer 130 is made of a material that is sufficiently rigid to serve as a stop for the expandable clamp 90 when the prepared end 210 of a corrugated cable 200 is inserted into the connector 10, but is also sufficiently flexible so as to deform when the expandable clamp 90 is axially advanced toward the tubular connector body 20 during transition between the first and second states of the connector 10.
- the deformable washer 130 may be made of a thin, soft metal, a plastic, or other like material that allows the washer 130 to perform its function described above.
- the cable connector 10 may be further comprised of a second insulator 150 disposed within the inner bore 26 of the tubular connector body 20 firstly from the first insulator 40.
- the second insulator 150 may be comprised of a first end 152, a second end 156, a central through-bore 158, and a flange 154 that is structurally configured to slidably engage the inner bore 26 of the tubular connector body 20 and configured to engage a shoulder 28 on the inner bore 26 of the tubular connector body 20.
- the connector 10 may further include a conductive central pin 170 disposed within the central through-bore 158 of the second insulator 150.
- the conductive central pin 170 may be comprised of a first end 172, a second end 174, and an axial socket 176 extending axially from the second end 174. [00146] Referring also to FIGS. 4 and 5, when the coaxial cable 200 is inserted into the connector 10, the axial socket 176 of the central pin 170 receives the exposed tip 212 of the center conductor 202 of the cable 200.
- a plurality of slits 178 running axially along the length of the socket 176 may be cut into the central pin 170 at predetermined intervals in the socket 176, thereby defining a plurality of fingers 179 between the slits 178 which are structurally configured to expand when the exposed tip 212 of the prepared cable 210 is inserted into the axial socket 176.
- the first surface 42 of the first insulator 40 may further comprise an annular rim 52 extending axially from the first surface 42, the annular rim 52 defining an annular hollow that is structured to receive the second end 174 of the central pin 170 under the condition that the compression cap 60 is axially advanced toward the tubular connector body 20 from the first state to the second state.
- axial advancement of the compression cap 60 toward the connector body 20 to the second state results in the first surface 42 of the first insulator 40 engaging the second end 174 of the conductive central pin 170, as well as axially displacing the conductive central pin 170 within the through-bore 158 of the second insulator 150.
- the second end 156 of the second insulator 150 may further comprise an annular recess 160 that is structured to receive the annular rim 52 of the first insulator 40.
- the second state is the configuration in which the connector 10 and the cable 20 are mechanically and electrically coupled. Specifically, in the second state, the connector 10 is electrically and mechanically coupled to the cable 200 to allow the cable 200 to transmit signals through the connector 10 and to the port (not shown) to which the connector 10 is further coupled. In the second state, the central pin 170 has been axially advanced beyond the first end 152 of the second insulator 150, so that the central pin 170 is connectable to a central socket of the port (not shown). Additionally, at least a portion of the deformable washer 130 is compressed and contained between the clamp push ring 120, the expandable clamp 90, and the tubular connector body 20. Some other portion of the deformable washer 130 may be disposed as shavings or other small particles (not shown) between the expandable clamp 90 and the tubular connector body 20.
- the connector 10 may be further configured such that axial advancement of the compression cap 60 to the second state results in the first end 126 of the clamp push ring 120 engaging the second end 24 of the tubular connector body 20. Also, axial advancement of the compression cap 60 to the second state results in a first shoulder 70 on the inner bore 66 of the compression cap 60 to engage an outer shoulder 30 on the tubular connector body 20. These contacts between the respective parts may function as additional stops when axially advancing the cap 60 onto the tubular connector body 20.
- the order of the movement of the parts within the connector 10, and the collapse of the outermost corrugation 214 of the prepared cable end 210 may vary from that described above and depicted in FIGS. 4 - 7.
- the first insulator 40 and conductive compression ring 80 have interference fits within the inner bore 26 of the tubular connector body 20. Therefore, axial advancement of these parts 40 and 80 within the bore 26 of the tubular connector body 20 is resisted by friction therewith.
- first insulator 40 and conductive compression ring 80 may axially advance within the bore 26 of the tubular connector body 20 before the outermost exposed corrugation 214 of the coaxial cable 200 collapses.
- axial advancement of the compression cap 60 toward the connector body 20 may first cause the first surface 42 of the first insulator 40 to engage the second end 174 of the conductive central pin 170 and axially advance the conductive central pin 170 within the through-bore 158 of the second insulator 150.
- the compression cap 60 may be further advanced axially on the tubular connector body 20 to result in the first surface 42 of the first insulator 40 engaging the second end 156 of the second insulator 150.
- the compression cap 60 may be further advanced axially on the tubular connector body 20 to result in the expandable clamp 90 axially advancing within the inner bore 26 of the tubular connector body 20 toward the conductive compression ring 80, thereby reducing the annular volume 89 between the first end 92 of the expandable clamp 90 and the second surface 86 of the compression ring 80, and collapsing the first exposed corrugation 214.
- the frictional resistance to motion of the first insulator 40 and conductive compression ring 80 within the tubular connector body 20 is approximately equal to the force required to collapse the outermost exposed corrugation 214, the displacement of these internal components 40 and 80 within the tubular connector body 20 and the collapse of the first most corrugation 214 of the cable 200 may occur concurrently as the compression cap 60 is axially advanced toward the connector body 20 from the first state to the second state.
- the connector 10 may include a first seal 12, such as an O-ring, that is disposed within a groove 13 (labeled in FIG. 8) on the outer periphery of the connector body and resides between the tubular connector body 20 and the inner bore 66 of the compression cap 60 under the condition that the connector 10 is in the second state.
- the connector 10 may further include a second seal 14 that is contained within the inner bore 66 and a second flange 72 of the compression cap 60.
- the components of the connector 10 may be dimensioned such that prior to the cap 60 being axially advanced toward the tubular connector body 20 there is a small gap 16 between the outer shoulder 124 of the clamp push ring 120 and the central shoulder 68 of the compression cap 60.
- the gap 16 is eliminated. The removal of the gap 16 places the second seal 14 in an axially compressed condition, thereby causing a radial expansion of the seal 14 that in turn provides effective sealing between the jacket 208 of the cable 200 and the inner bore 66 of the compression cap 60.
- the connector 10 may be provided with a fastener 180, such as a nut for engagement to the port (not shown).
- the fastener 180 may include a seal 182 for sealing to the port.
- the connector 10 may be provided with male threads for connection to a female port.
- the connector 10 may also be configured as an angled connector, such as a 90 degree elbow connector.
- FIG. 8 is a cross sectional view of the exemplary compression connector 10 during insertion of the prepared segment 210 of annular corrugated coaxial cable 200.
- the coaxial cable 200 of one embodiment is comprised of a hollow center conductor 202 surrounded by an insulator 204, a corrugated outer conductor 206 surrounding the insulator 204, and an insulative jacket 208 surrounding the outer conductor 206.
- the prepared end 210 of the coaxial cable 200 is comprised of an exposed length of the center conductor 202, the insulator 204, and the corrugated outer conductor 206.
- the outer conductor 206 is exposed by removing the insulative jacket 208 around the conductor 206 until at least a first exposed outer conductor corrugation 214 between first and second recessed valleys 216 and 218 and a second exposed outer conductor corrugation 220 between second and third recessed valleys 218 and 222 are exposed.
- the prepared end 210 should be configured (i.e. cut) such that the leading edge 226 of the outer conductor 206 is within one of the recessed valleys of the corrugated outer conductor 206, the advantages of which will be described in detail below.
- the insulator 204 is made of a soft, flexible material, such as a polymer foam.
- the connector 10 of the various embodiments described herein is advantageous in that it is simple to install in a factory or field setting and it is reliably effective at establishing and maintaining strong contact forces between the connector 10 and the annular corrugated coaxial cable 200.
- the connector 10 of one embodiment includes the conductive pin 170 and the insulator 150, the insulator 150 being disposed within the connector body 20 and slidably engaged with the inner bore 26 of the connector body 20.
- the insulator 150 is disposed around the conductive pin 170 so as to hold the conductive pin 170 in place. Further, the insulator 150 is positioned radially between the conductive pin 170 and the connector body 22.
- the conductive pin 170 provides the connection to the hollow center conductor 202 of the prepared coaxial cable segment 210 to which the connector 10 is being connected, and the insulator 150 electrically insulates the conductive pin 170 from the connector body 22 and the connector body 20.
- the conductive pin 170 may have outwardly expanding flexible tines 332 to engage the inner diameter of the hollow conductor 202, and a retaining element 334 to secure the tines 332 from axial movement.
- the inner bore 26 of the connector body 20 further comprises an engagement region 336, shown in FIG. 8 and enlarged in FIG. 11.
- the engagement region 336 comprises a first region 335 that extends radially inward from the inner bore 26 of the connector body 20 and a second region 337 that extends both radially inward and axially toward the prepared end 210 of the coaxial cable 200.
- the engagement region 336 functions as a compression surface, similar to the compression surfaces 92 and 86 in embodiments described above, in that the engagement region 336 assists in the collapse of the corrugated outer conductor 214.
- second region 337 has an acute angle a from the longitudinal axis 2. The angle may be between 5 degrees and 60 degrees.
- the angle of the second region 337 is approximately 45 degrees.
- the proximal end of the engagement region 336 may further include a planar face 338 substantially perpendicular to the longitudinal axis 2.
- the planar face 338 and the engagement region 336 work in concert to engage and deform the corrugated outer conductor 214 until it collapses on itself to form the collapsed corrugated outer conductor 215, under the condition that the connector is transitioned from the first state, shown in FIG. 8, to the second state, shown in FIG. 9.
- the second end 24 of the connector body 20 further comprises a beveled edge 342 to assist in the functional engagement of the connector body 20 with the clamp
- the beveled edge 342 permits the clamp 90 to slidably engage the beveled edge 342 so as to ensure that the outer periphery 95 of the clamp 90 slidably engages the inner bore 26 of the connector body 20 under the condition that the compression cap 60 is axially advanced toward the connector body 20 from the first state to the second state.
- transition from the first state to the second state results in the advancement of the compression cap 60 so that the shoulder 68 of the compression cap 60 engages the clamp push ring 120, which engages the clamp 90, which engagement axially advances the clamp 90 toward the connector body 20, such that the clamp 90 engages the beveled edge 342 of the connector body 20 to guide the outer periphery 95 of the clamp 90 to slidably and functionally engage the inner bore 26 of the connector body in the second state.
- the clamp 90 may also have a beveled edge 382 on the first end 92.
- the beveled edge 382 functions as a compression surface, similar to the compression surfaces 92 and 86 in the embodiments described above.
- the beveled edge 382 is structurally compatible with the engagement region 336, such that the beveled edge 382 and the engagement region 336 work in concert to engage and deform the corrugated outer conductor 214 under the condition that the connector is transitioned from the first state to the second state.
- the clamp 90 may have a plurality of elastic members 108 disposed around the outer periphery 95 thereof, as shown in FIGS. 8 and 9.
- the elastic members 108 may be tension rings that serve to hold the individual sectors of the clamp 90 in a slightly open or expanded position.
- the tension rings may be fabricated from metal or plastic.
- the connector 10 of the various embodiments may be joined to the coaxial cable segment 200 generally in the following manner.
- the corrugated coaxial cable segment 200 may be prepared for insertion by cutting the cable at one of the corrugation valleys, and specifically at the first corrugation valley 216, or at least near the first corrugation valley 216. This offers an advantage over many prior art cable connectors that require cutting the corrugation at a peak, which can be difficult.
- the cable 200 can be prepared according to the respective descriptions provided above.
- the connector 10 is thereafter pre-assembled to its first state.
- the internal elements 14, 120, 90, and 130 may be held in axial compression by inserting the seal 14 into the bore 66 of the cap 60 until it abuts the second flange 72; inserting the plush clamp ring 120 into the bore 66 of the cap 60 until it abuts with the seal 14; inserting the clamp 90 until it abuts with the clamp push ring 120; and inserting the washer 130 into the bore 66 of the cap 60 until it abuts with the clamp 90.
- the internal elements 150 and 170 can also be held in axial compression by inserting the insulator 150 into the bore 26 of the connector body 20 until the insulator abuts the shoulder 28 on the inner bore 26; inserting the conductive pin 170 into the central through-bore 158 of the insulator 150.
- the first insulator 40 may be inserted within the bore 26 of the connector body 20 and thereafter the compression ring 80 may be inserted onto the tubular mandrel 46 of the first insulator 40.
- the compression cap 60 and the connector body may thereafter be initially coupled together by slidably engaging the compression cap 60 with the body 20 to establish the first state of the connector 10.
- the bore 66 of the cap 60 slidably engages the outer periphery of the connector body 20, until the washer 130 engages not only the clamp 90 within the compression cap 60 but also engages the second end 24 of the connector body 22, thus holding the respective components in place in the first state.
- the insertion of the coaxial cable 200 to the first state may be performed by hand.
- the corrugated coaxial cable 200 is the annular variety, although the invention is not so limited.
- the annular corrugations in the outer conductor 206 do not allow the clamp 90 to be threaded into place, as may be the case for spiral corrugated coaxial cable segments. Therefore, the individual sectors of the clamp 90 must spread radially outward to allow the clamp 90 to clear the corrugated sections of the outer conductor 206 in the coaxial cable 200.
- the elastic member 108 is flexible and allows the clamp 90 to spread radially outward while constraining individual sectors of the clamp 90 from becoming free. As the cable 200 is pushed into the connector 10 through the compression cap 60, the clamp 90 extends radially outward to clear the corrugated peaks and valleys of the outer conductor 206, then settles radially inward into the corrugated valleys.
- the transition of the connector 10 from the first state to the second state may be performed by hand or in most cases by a hydraulic tool (not shown).
- the tool engages the cap 60 and the connector body 20 and squeezes them together, thereby moving the connector 10 to the second state. As the hydraulic tool axially displaces the cap 60 and the body
- the leading edge 226 of the first exposed outer conductor corrugation 214 encounters the engagement region 336 of the connector body 20 and is deformed in a manner that provides superior electrical contact.
- the planar face 338 and the engagement region 336 cause the outer conductor 214 to fold upon itself and become wedged between the engagement region 336 of the connector body 20 and the clamp engagement region 382 of the clamp 90.
- the folding action creates two thicknesses of conductive outer conductor 214, as the conductor 214 is collapsed onto itself to create the collapsed outer conductor 215, which significantly improves electrical contact.
- FIG. 10 illustrates the folded conductor 215 in an enlarged view.
- the connector body engagement region 336 including sections 335 and 337, folded outer conductor 215, and clamp engagement region 382 are depicted in slightly exploded view to delineate the various components. In actuality, the components are tightly compressed together.
- FIG. 10 further illustrates the arrangement of components that provide frictional forces to lock the connector 10 in place.
- the outer diameter of the clamp 90 and the inner diameter of the connector body 20 are sized to provide a slight radial interference fit (RIF).
- RIF radial interference fit
- FIG. 11 depicts a scenario to illustrate the folding action of the first exposed outer conductor corrugation 214.
- the outer conductor 214 is trimmed approximately at the first corrugation valley 216.
- the planar face 338 of the connector body 22 passes over the leading edge 226 of the outer conductor 214 and contacts the conductor 214 approximately near the trailing inflection point 392 of the outer conductor 214, causing the conductor 214 to fold over on itself, as depicted by the arrow.
- One advantage of this arrangement is that an operator preparing the cable segment 200 for insertion does not need to trim the cable 200 precisely at a corrugation valley; there is provided ample leeway on either side of the valley.
- the first region 335 that extends radially inward from the inner bore 26 of the connector body 20 may further comprise a retention feature 394 to further secure the deformed corrugated outer conductor 215 in a radial direction.
- the retention feature 394 is an annular recess in the first region 335, such that the first region 335 axially indented.
- the clamp 90 may include a complimentary retention feature 396.
- the collapsed corrugated outer conductor 215 is sandwiched not only along the complimentary compression surfaces 336 and 382, but also between the retention features 394 and 396.
- the connector is in the second state.
- the clamp 90 further comprises a beveled edge 372, in addition to the beveled edge 382 described above.
- the beveled edges 372 and 382 are positioned on opposing leading corner edges of the clamp 90, beveled edge 382 being positioned radially inward of the beveled edge 372.
- Beveled edge 372 is angled at an acute angle from the common axis 2, and the angle of the beveled edge 372 is less than the angle of the beveled edge 382 from the common axis 2.
- Beveled edges 372 and 382 function as compression surfaces under the condition that the connector is transitioned from the first state to the second state.
- Corresponding compressions surfaces are found in the compression ring 80 of the embodiment of FIG. 14.
- the second surface 86 of the compression ring 80 further comprises angled surfaces 381 and 371 that oppose one another and generally form a v-like shape in the second surface 86.
- the angled surfaces 381 and 371 correspond to and compliment the beveled edges 382 and 372, respectively.
- the angled surface 371 is angled from the common axis 2 at approximately the angle of the beveled edge 372.
- the angled surface 381 is angled from the common axis 2 at approximately the angle of the beveled edge 382.
- the compression surfaces, 372 and 382, on the clamp ring 90 functionally engage the corresponding compression surfaces, 371 and 381, respectively, on the compression ring 80 to compress therebetween the first exposed outer conductor corrugation 214 of the cable 200 so that the corrugation 214 collapses on itself.
- the result is that the collapsed corrugation 215 is pressed between the compression surfaces 372 and 371 at one angle and also pressed between the compression surfaces 382 and 381 at another angle, thus forming the v-like shaped compression.
- This v-shaped compression provides both axial and radial compression of the connector 10 to facilitate advantageous mechanical and electrical coupling of the connector 10 to the cable 200 in the second state and to prevent the connector 10 from disengaging without undue force once the connector 10 is moved to its second state.
- the compression ring 80 comprises the first surface 84 that engages the second surface 48 of the first insulator 40.

- FIGs 8-13 depict a female type connector for connection to a separate male component.
- FIGs 8-13 depict a female type connector for connection to a separate male component.
- the structure and functionality pertaining to all connector embodiments 10, 1000 shown in any of FIGs 1-21 can and should be designed to maintain a coaxial form across the connection and have similar well- defined impedance as matched with the attached cable.
- variously sized connectors 10, 1000 can and should be made to effectively operate with correspondingly sized cables.
- connectors 10, 1000 can be operably adapted to DIN-type connectors, BNC- type connectors, TNC-type connectors, N-type connectors, and other like coaxial cable connectors having structure and functionality that is operably commensurate with the connector embodiments 10, 1000 described herein.
- FIG. 16 shows a blown-up cross-section view of a portion of an embodiment of a connector 10 as attached to a coaxial cable 200.
- the coaxial cable 200 may include an inner conductor 202 surrounded by an inner dielectric insulator 204.
- the inner conductor 202 may be formed of solid conductive material, or may be a hollow conductive member.
- the inner dielectric insulator 204 may be similar to those inner dielectric insulators discussed previously.
- An outer conductor 206 may surround the inner dielectric insulator 204.
- the outer conductor 206 may be tube-like, and may be solid in form or may be comprised of various braided or wrapped conductive layers.
- the geometry of the outer conductor 206 may be smooth, corrugated, helical, or other operable configurations.
- the cable 200 is shown attached to the connector 10 in a second state, the cable components 200 having been compressed into secure mechanical position within the connector 10 from a first state via axial compression.
- the first insulator 40 resides proximate the conductive compression ring 80, which, in turn, resides proximate the clamp 90 of the connector 10, with a portion of the outer conductor 206 of the cable 200 mechanically sandwiched between the cooperating compression surface 381 of the conductive compression ring 80 and the corresponding cooperating compression surface 382 of the movable clamp 90.
- the clamp 90 may be solid or slotted.
- the sandwiched section of the outer conductor 206 comprises a collapsed corrugation portion 215a having a rogue leading edge 226a that hangs away from or otherwise resides apart from the rest of the collapsed corrugated portion 215a.
- a connector embodiment 10 When a connector embodiment 10 is attached to a coaxial cable 200 in a manner that permits the positioning of a rogue conductive member, such as the hanging leading edge 226a, there may be undesirable ramifications related to passive intermodulation (PIM) and return loss, with respect to matching the impedance properties of the connector 10 to the impedance properties of the attached cable 200. Unmatched impedance can lead to problems in signal integrity disrupting signal transmission through the cable 200 and the connector 10 and on to connected communications devices. As a result, there is a need for structure and functionality that helps prevent the presence of rogue conductive members within a coaxial cable connector.
- PIM passive intermodulation
- Connector embodiments 10 may be provided with structural components to help guide conductive members into desirable locations as the conductive members are displaced during compressive attachment of the coaxial cable 200 to the connector 10.
- FIG. 17 depicts another connector embodiment 10 having a conductor displacement guiding member 500.
- the conductor displacement guiding member 500 exists as a sleeve integrally extending from the first insulator 40.
- embodiments of a conductor displacement guiding member 500 may also exist as independent components, such as separate rings and bushings, and/or as a structural feature integrated with the conductive compression ring 80.
- a conductor displacement guiding member 500 may be formed of either conductive or non-conductive materials, or a combination thereof, and considerations with respect to impedance matching are important to the location and material make-up of conductor displacement guiding member embodiments 500.
- the embodiment of the conductor displacement guiding member 500 shown in FIG. 17 may be formed of a
- polyetherimide plastic such as an Ultem® resin
- advantageous properties including a high dielectric strength, natural flame resistance, and low smoke generation, as well as high mechanical properties and acceptable performance in continuous use to 340°F (170°C).
- An embodiment of a conductor displacement guiding member 500 may be located within a connector 10 in a manner permitting prescribed contact with conductive members, such as an outer conductor 206, to help guide the conductive member into a desirable location as it is displaced during attachment of the coaxial cable 200.
- the conductor displacement guiding member 500 may include guiding structures, such as the ramped guiding surface 581, configured to contact and then act upon the guided leading edge 226b as the outer conductor 206 is displaced, such that a guided collapsed corrugation portion 215b operably resides between cooperating surfaces 381 and 371 of the conductive compression ring 80 and the movable clamp
- the conductor displacement guiding member 500 helps guide the leading edge 226b to a desired location tucked up near the collapsed corrugation portion 215b.
- the conductive displacement guiding member 500 aids in locating the outer conductor 206 such that it is centered, and that the end 226b of the outer conductor 206 folds into a collapsed corrugation portion 215b more predictably.
- connector embodiments of the connector 10 do not suffer the impedance, PIM, and return loss drawbacks associated with connectors having rogue conductive members, such as the rogue leading edge 226a shown in FIG. 16. Return loss and PIM are minimized through guided locating of the leading edge 226a of the outer conductor 206, thereby facilitating impedance matching.
- Connector embodiments 10 including conductor displacement guiding members 500 may operably incorporate structure similar to the connector structure described above with respect to FIGs 1-15. Consideration toward cost and ease of assembly can guide those in the art to incorporation of conductor displacement guiding members 500 that ensure good connector 10 performance.
